TOaliwhom it may concern:

Be it known that I, FnANcrs MmsnL, a i citizei'i of the United States,residing at Dovcr, in the countv of Stratiord. and State i of Newl'lmnpshire, have invented a new and llSCfUl Pl'll1tlflg-l lt'SS, ofwhich the. following is a specification.

This invention relates-to that class of rotnry printing presses whichare designed to print'upon separate sheets.

The especial object of this invention to termittent, adjustable paperfeeding mechmiisin for supplying the press with variable lengths oisheets.

Fin-um objects and advantages oi the invention will appear hereinafter.

Reference is to .be had to the accompanying two sheets of drawings whichshow one form otthe invention, and in which,

Figure I isa plan view ofsufiicient )nrts of a printing press toillustrate the app iention of my invention. thereto. Fig. 2 is asidei-t-hols'mne. Fig. 3 is n partial end View thereof, and Fig 4 is n;detail view of the deliverygrippers.

in producingthe coa-rsergrades of printing, and-even in producing someof the iiner )rintediproducts, a rotary printing ress may 'be operatedat much higher speed t inn other styles of presses. This isdue t'o.thefact that the paper rims directly through the hinting only limited tothe speed at which paper can be'.' fed rOn this account, rotary printingpressesnre now used for printing newspapers orfor other products whichrequire longruns. In actunlipractice, however, the rotary prints, ing.presses have notes yet con "into general use for; ordinary job pr neg;or other purposes Where one, .pres. is; eduired to pi'oduee-nyarietly ofproducts. l iis is due to theifacflthat rotniry printing presses asheretofore.constructed, have not usually been equipped to print on morethan one size oi sheet, and the speed of rot-cry presses which havebeen, designed. to priut-sepm'ate sheets have been' 'limited to thespeed at WhlGlitlie sepg at l cots-could be delivered from the n eehinmoi-especial object of my present invention ist-to-provide a. rotarypress which ma be readily setor.iidi'usted to produce ovum et'y ofprodu9ts.--,-,"o accomplish these reis severed into sl'ieets beforebeing fed to the impression cylinder. mechanism is oi specialconstruction, and although intermittent- .in action, it is controlledbytwo separate pawl and ratchet mechanisms, so :is to produce asubstantially uniform. unwinding of the paper from the paperroll. hepawl and ratchet mechanisms are cup-ubleoi quick and simple adjustments.to produce any desired length of sheets, which sheets are severed fromthe web of paper. by the ordinary cutting cylinders, and are carried. bytapes to the impression cylinder onto which they lLl'G taken by grippersand are printed by passing between the impression cylinder and printingcylinder.

From the impression.cylinder the printed sheets are taken onto agiitl'iering cylinder which will forward successive sheets to thedelivery, or which may be made to collect several successive sheets. Inthe present instance, the machine illustrated, is arranged to collectsix sheets upon the gathering cylinder. 'lhese sheets then run ontoareel rociiting carriage which moves forward at the same speed as the.paper-feed. The leading ends of the sheets are seized by-delivergrippers, which grippers hold the sheets 0 paper while the carriage isbeing moved'back into position to receive a succeeding number of sheets.The backward movement of the carriage takes place. at it much slowerspeed. than its forward motion. That is to say, the ea.r ridge is movedback from under the sheets at a slow even speed, so thatthe sheets willbe The paper feeding' delivered smoothly and efficiently uponthedelivery table. I

Referring to the aceomnnying drawings for adetail description 0 aprinting press embodying my invention, as shown in F1 1'-,

A designates the side 'fmn'ies. Journale at one end of the side framesA, as shown in jonrna-led iu '\-erticnlly movable boxes 14'.

Passing through the boxes 14 is a clamping shaft 15 having eccentricsfor clamping the 1 upper feed-roll downin operative position, or-

for holding the same up when the uplift-ii ibeing threaded into place.From t e faeil are carried forward between cormtant-ly run rolls -12 and13 the paper passes between the ning tapes '1, from which the sheets aretaken by grippms (ion the impression (f' VllIHlltP'I. Cooperating withthe inuression cylinderl is the printing cylinder 6 having the usualinking mecininisin, indicated by dotted lines. From the im )ressioncylinder I the suceessiv eiy printed sheets are taken by grip iers Gonto the gatl'iering cylinder B. \i en the desired number of sheets hasbeen eollected on thegathering cylinder B, they are stiip )edfliereirorn by the usual switeh S, which may be operated from thecaIn-shaft of the 1n:-Is.chine by any ordinary ciqnneetions which neednot be herein shown or described.

the sheets are stripped from t'he'gatherin; cylinder B they drop downonto .a. delivery carriage F which starts forward at the same speed asthe travel of the sheets. The leading ends of the sheets are presentedto the delivery gri ipels, (the construction and icration of which vwillbe hereinafter de- .hcd) and the complete sheetshm'delii'ered upon thedelivery table Z'When the delivery ige F is moved back into position to'receive a'sneceeding number of sheets. The gearing for operating theseparts is most clearly illustrated in Fig. 1 of the drawin s.' As shownin this figure, the printing-cylin er ('1', impression-cylinder I, andgathering-cylinder B are geared to turn together. So cured on the shaftof the im )re'ssion cylinder l is a small pinion 27 whit: .meshes with agear 28 secured on the cam-shaft 29. In the present instance, the gear27 is onesixth of the size of the gear 28, so that the cam-shaft will heturned once'for each sixrevplution's' of the impression cylinder, or thecam-shaft 29 will make one'turn during the printing of six succeedingsheets. Meshing with and driven from the gear which is secured on theshaft of the gathering cylinder B is a pinion 18 journaled on a studsecured-in the side'- frames. Mounted upon .andturning with the gear 18is a-slotted arm 19;;- 'Adjusta'hly fastened in the slotted arm 19 is acrank-pin 21 which is connected by a link 22 to a crossthe movable cr!SS hefld, and that the ways on the frame of the machine.- Pivoted on acrankin in the movable cross-head are 50 links23 an 24 which areconnected'at their outer ends topawlwarrying arms having 7,paw'lsengagmg the ratchet-disk 25 secured upon the shaft. of thefeed-roll 12.

By :ineans. of'this construction it will be seen that the (Tank-pin 21will reci )rocate links 23 and 24 will swing the pawl-carrying armsinrelatively opposite directions. That is to say, thesepawl-carryingarms will open and" shut iike the jaws ofnpair of scissors,so that whil'c onespawl-rnrrymg arm. is moving in' such direction astoadvanee the ratchet-disk its idle "or return strolic.

To 7 adjustthis paper feeding" i'ncchanisin to produce dill'ercnt lengths ofsheets, the crankpin 21 may he set or adjusted. to have dill'er entlengths ol throw to move the cross head different distances as required.1n some cases, in order to obtain a still finer adjustment of the lengthof sheet it is desirable to adjust one pawl-carrying arm independentlyof the other, so that its throw may be increased or decreased by onetooth of the ratchet wheel 'lo aecomplishthis lpurpose, the pin 26 whichconnects the lin with one of the pawl-carrying arms may be madeeccentric, so that by setting or tul'ning I this eccentric iin, Ins finean adjustment-as 35' required may he secured.

The operation of the several iarts of a printing press constr eted aceoring to my invention have been fully explained in describin theconstructions in detail, that it is not be leved necessary to describethe opera tion of the printing press as a Whole.

Although I have disclosed a delivery mechanism, I do not claim itherein.

I am aware that numerous changesmay be made in practicing my inventionby those who are e illed in the art without departing from the seethereof as expressed in the claims, and t at my invention may be appliedto printi presses of somewhat difl'erent ty 0 from at hereinillustrated.v For exam e, my improved form of paper-feeding eet deliverymechanism 18 equall a plicable to a perfecting press in whicli tlihsheets are printed upon both sides. I do not wish, therefore, to belimited to the particular construction I have herein shown anddescribed, but

What I claim and desire to secure by Lettars Patent of the United Statesis: I. In a printing press, the combination of a printing con la, apaper feeding mechap ism, two sets 0 intermittently operatlng corenections acting successively to produce a sub"- 'stantially continuouspaper feeding action, and means for adjusting the same to supplyvariable lengthsof sheets.

e 2. In a printing press, the combination of a printing couple, a paperfeeding mechanism, and two sets of intermittently operating pawl andratchetmechanisms acting successively to produce a substantiallycontinuous paper fee ing action.

3. In a printing press, the combination of, a printing couple, a paperfeeding mechanism, andan actuating mechanism therefory'' comprising aratchet wheel and two oppositel moving crank -actuated levers carryingpaw s acting successively on the ratchetwheel, to reduce a substantiallcontinuous paper fee ng action. I

4. In a printing press, the combination of a printing c'ouple,-a paperfeeding mechanism, and operating connections therefor, com-.

prising a ratchet wheel, a pair of awl car mg levers pivotedconcentricall with t e ratchet wheel, a crank-actuated cross-head, alink connectin each pawl-lever with the cross-head, said iinks beingarranged on opposite sides of the center of the ratchetwheel, and meansfor adjusting the throw of the crank which operates the cross head toproduce'a variable length of paper feed.

5. In a printing press, the combination of a printing couple, a paperfeedilig mechanism, and actuating connections therefor, comprising aratchet wheel, ,two pawlcarrymg arms pivoted concentrically therewith, a

crank-actuated cross-head, a'link connecting each arm with thecross-head, said links being arranged on op osite sides of .the centerof the ratchet-whee means for adjusting the throw of the crank whichactuates the crosshcad to vary the length of the paper feed, and

an adj ustable connection between one of the awl. carrying arms and itslink to provide or finer adjustments of the paper flied.

In testimony whereof I have hereunto set my hand, in t witnesses.
